Improvement in churn-powers



PATENT GFEIGE.

BENJAMIN F. FRAMPTON, OF BUNXATAWNEY, PENNSYLVANIA.

IMPROVEMENT IN CHURN-POWERS.

Specification forming part of Letters Patent No. 117,166, dated July 18,1871.

To all whom 'it may concern:

Be it known that I, BENJAMIN F. FRAMPTON, of Punxatawney, inthe countyof Jefferson and State of Pennsylvania, have invent-ed a new andImproved Power for Ghurns; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing making a part of this specifica-tion, in which-VFigure l is a side elevation; Fig. 2, an end elevation. Fig. 3 is asectional elevation of the 4shaft Iand drums, and Fig. et is a sideelevation of the brake for the Sha-fn.

My invention is an improvement in the class of churn-propellers whichincludes as a distinguishing feature a weight suspended by a cord from awinding-drum. My invention consists in an arrangement, hereinafter fullydescribed, of parts whereby, as one weight descends, it not onlyoperates the churirdasher, but also raises another lesser weight, which,when the former has reached the floor, is in turn allowed to descend andcontinue the movements of the dasher.

Referring to the drawing, a is a churn; b, the dasher; c, a walking-beamthat works the dash er through the medium of a pitman, d, and is itself'worked by a pitman, c, thatis jointed to a crank, f, formed in a shaft,g, mounted crosswise of a pair of vertical standards, A B, and connectedby gearing h 'L' with a second shaft, j, mounted in the same standards.The shaft j bears two drums, k l, one fixed, the other loose. rlhe loosedrum Z is provided with a spring-pawl, m, which when pressed inwardengages with a circular ratchet, n, secured to the side of a disk, o,that is iiXed on the shaft j. To the periphery of the drum lis attachedone end of a cord, p, the same passing thence upward over ashea-ve, q,mounted on a pin that extends from the end of the crossbar r, whichconnects the upper extremities of the standards A B. When the drum l isturned backward the cord p is wound tightly around the drum and theweight c, which is fastened to the end of said cord, is thereby raised.The cord presses the pawl m inward, but the latter only slips over theratchet a as long as the drum l is p rotated backward. When the weight chas been raised to the sheave q the backward rotation of the drum lshould cease and the weight allowed to descend. Thereupon the pawl mengages with the ratchet n and effectsthe rotation of the shafts g and jand the working of the dasher. The drum 7c turns with the shaft j, andconsequently winds 'up the lesser weight s Aby means of the cord tpassing over the sheave u. The weight s reaches the sheave u at the sametime that the weight c reaches the iloor. The unwinding of the cord pfrom the drum l allows the pawl m to separate from the ratchet a, and assoon as this takes place the weight s begins to descend and t0 turn theshaft g in the opposite direction. rIhe direction, however, in whichsaid shaft turns is a matter of no consequence, as it works the dasherequally well either way. rlhe weight s continues to operate the dashertill it reaches the floor. By this arrangement the same effect isproduced/as though the distance traveled by the weight c were twice whatit is. By employing two weights, as described, the frame is as it werebalanced and rendered steady without the aid of devices for securing thesaine to the floor or other support, and the friction or strain on thedrivingshaft is not applied to one end alone so as to cause it to wearunequally. A brake, u, Fig. 4, is hung to one side of the standard B. Bymeans of a screw, a', said brake can be pressed against the rim of thedisk o. rlhis is done when turning the drum backward to wind up theweight c, and the object of doingit is to prevent the backward rotationof the shaft j at the same time.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The driving-shaft j, liXed drum 7c, loose drum Z, pawl m, ratchet n,gear-wheels h c', pulleys q u, small weight s, and large weight c,arranged in connection with the frame A B 1", as shown and described.
